TABLE 5.
Effect of amino acid (AA) and glycomacropeptide (GMP) diets on postprandial indexes of protein and glucose metabolism1
| Test | AA diet | GMP diet | P value2 |
| Blood urea nitrogen (mmol/L) | 4.2 ± 0.3 | 3.4 ± 0.2 | 0.02 |
| Creatinine (μmol/L) | 73 ± 5.5 | 73 ± 4.6 | 1.00 |
| Total protein (g/L) | 68 ± 1.4 | 67 ± 1.4 | 0.27 |
| Albumin (g/L) | 44 ± 0.9 | 44 ± 0.8 | 0.84 |
| Prealbumin (g/L) | 317 ± 7.5 | 310 ± 7.3 | 0.22 |
| Insulin-like growth factor I (nmol/L) | 13.5 ± 1.3 | 13.7 ± 1.5 | 0.14 |
| Insulin (pmol/L) | 84 ± 22 | 116 ± 34 | 0.05 |
| Glucose (mmol/L) | 4.5 ± 0.1 | 4.8 ± 0.1 | 0.14 |
| CO2 content (mmol/L) | 26 ± 0.6 | 28 ± 0.6 | 0.01 |
1
Values are means ± SEMs; n = 11, except total protein and insulin for which n = 10; all values are within normal range. Values are for serum except those for insulin-like growth factor I and insulin, which used plasma.
2
Difference between the last day of the AA diet (day 4) and the GMP diet (day 8) by paired t test, pairing on subject.
